Omron G9KA PCB Power Relays

OMRON G9KA Series PCB Power Relays utilize a unique double-break, twin-contact structure for ultra-low contact resistance of ≤0.2mΩ. These power relays feature high-conductivity material and an optimized terminal design to ensure superior heat dissipation, making them highly reliable under extreme current loads. The plunger-type mechanism provides high durability and low power consumption, perfect for next-generation energy systems. The G9KA series PCB power relays now offer an optional auxiliary contact for enhanced safety monitoring. Typical applications include power conditioner inverters, industrial inverters, and fast EV chargers.
